Item Clinical Challenges in Pediatric Ventilation Liberation: A Meta-Narrative Review(Wolters Kluwer, 2022) van Dijk, Jefta; Blokpoel, Robert G. T.; Abu-Sultaneh, Samer; Newth, Christopher J. L.; Khemani, Robinder G.; Kneyber, Martin C. J.; Pediatrics, School of MedicineObjectives: To map the evidence for ventilation liberation practices in pediatric respiratory failure using the Realist And MEta-narrative Evidence Syntheses: Evolving Standards publication standards. Data sources: CINAHL, MEDLINE, COCHRANE, and EMBASE. Trial registers included the following: ClinicalTrials.gov, European Union clinical trials register, International Standardized Randomized Controlled Trial Number register. Study selection: Abstracts were screened followed by review of full text. Articles published in English language incorporating a heterogeneous population of both infants and older children were assessed. Data extraction: None. Data synthesis: Weaning can be considered as the process by which positive pressure is decreased and the patient becomes increasingly responsible for generating the energy necessary for effective gas exchange. With the growing use of noninvasive respiratory support, extubation can lie in the middle of the weaning process if some additional positive pressure is used after extubation, while for some extubation may constitute the end of weaning. Testing for extubation readiness is a key component of the weaning process as it allows the critical care practitioner to assess the capability and endurance of the patient's respiratory system to resume unassisted ventilation. Spontaneous breathing trials (SBTs) are often seen as extubation readiness testing (ERT), but the SBT is used to determine if the patient can maintain adequate spontaneous ventilation with minimal ventilatory support, whereas ERT implies the patient is ready for extubation. Conclusions: Current literature suggests using a structured approach that includes a daily assessment of patient's readiness to extubate may reduce total ventilation time. Increasing evidence indicates that such daily assessments needs to include SBTs without added pressure support. Measures of elevated load as well as measures of impaired respiratory muscle capacity are independently associated with extubation failure in children, indicating that these should also be assessed as part of ERT.Item Weaning of Moderately Preterm Infants from the Incubator to the Crib: A Randomized Clinical Trial(Elsevier, 2019-01) Shankaran, Seetha; Bell, Edward F.; Laptook, Abbot R.; Saha, Shampa; Newman, Nancy S.; Kazzi, S. Nadya J.; Barks, John; Stoll, Barbara J.; Bara, Rebecca; Gabrio, Jenna; Childs, Kirsten; Das, Abhik; Higgins, Rosemary D.; Carlo, Waldemar A.; Sánchez, Pablo J.; Carlton, David P.; Pavageau, Lara; Malcolm, William F.; D’Angio, Carl T.; Ohls, Robin K.; Poindexter, Brenda B.; Sokol, Gregory M.; Van Meurs, Krisa P.; Colaizy, Tarah T.; Khmour, Ayman; Puopolo, Karen M.; Garg, Meena; Walsh, Michele C.; Pediatrics, School of MedicineOBJECTIVE: To assess whether length of hospital stay is decreased among moderately preterm infants weaned from incubator to crib at a lower vs higher weight. STUDY DESIGN: This trial was conducted in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Infants with gestational ages 29-33 weeks, birthweight <1600 g, and in an incubator were randomly assigned to a weaning weight of 1600 or 1800 g. Within 60 to 100 g of weaning weight, the incubator temperature was decreased by 1.0°C to 1.5°C every 24 hours until 28.0°C. The infants were weaned to the crib following stable temperature at 36.5°C to 37.4°C for 8 to 12 hours. Clothing and bedcoverings were standardized. The primary outcome was length of hospital stay from birth to discharge; secondary outcomes included length of stay and growth velocity from weaning to discharge. Adverse events were monitored. RESULTS: Of 1565 infants screened, 885 were eligible, and 366 enrolled-187 to the 1600-g and 179 to the 1800-g group. Maternal and neonatal characteristics did not differ among weight groups. Length of hospital stay was a median of 43 days in the lower and 41 days in the higher weight group (P = .12). Growth velocity from completion of weaning to discharge was higher in the lower weight group, 13.7 g/kg/day vs 12.8 g/kg/day (P = .005). Groups did not differ in adverse events. CONCLUSIONS: Among moderately preterm neonates, weaning from incubator to crib at a lower weight did not decrease length of stay, but was safe and was accompanied by higher weight gain after weaning.
